I would like a map editor for minecraft that can import image files, preferably either numbered bitmap files or perhaps an image file with layer data. each image would correspond to one z level, and various colors would represent different block types. i vaguely remember there was a map editor capable of this for old alpha maps some time ago. it needs to work with SMP map saves, and should be able to export this same layer data to number files for editing. does anyone know of an editor that already does this?
